First record of asian cardamine occulta hornem. (brassicaceae) in Poland

Abstract

Cardamine occulta is an annual or biennial plant native to Eastern Asia. It was introduced to Europe in the second half of the 20th century. So far, it was recorded in 16 European countries, usually in anthropogenic habitats of urban areas. Abundant populations of C. occulta have been found in the surroundings of Lake Constance in Germany, Austria, and Switzerland. In this study, I present the first record of C. occulta in Poland. It was found in two stands in the city of Kraków, southern Poland, in November 2019, growing in a flower bed and flower ponds. The distribution of the species is mapped using the ATPOL cartogram grid and its status in Poland is briefly discussed.
